Boxelder bugs
Boxelder Bug Control in Fort Collins
Per CSU Extension, females lay eggs on and around female boxelder trees, and the nymphs feed on low plants and then on seeds. Come fall, adults head for protected places like houses, gathering on south and west exposures. They rarely bite, but they stain light surfaces and smell when crushed. CSU suggests removing a problem tree when practical, sealing entry points, and using soapy water or a vacuum on the ones that get in.
